Abstract: Erosion of parts owing to cavitation in the part-load region of operation of a centrifugal pump is reduced or eliminated by equipping the pump with an annular diffuser which is installed upstream of the annular intake of the impeller. The impeller portion immediately downstream of the inlet edge, where the vanes begin, is bounded by a surface which diverges at an angle of 8 to 20 degrees, as considered in the direction of fluid flow in the impeller. The diffuser has a smaller first cross section which is remote from and a larger second cross section which is nearer to the impeller. The area of the smaller cross section is between one-half and nine-tenths of the area of the larger cross section. If the diffuser has a conical internal surface, the angle of divergence of such conical surface (as considered in the direction of fluid flow toward the impeller) is between 5 and 15 degrees. If the diffuser is internally stepped, the ratio of its length to the diameter of the larger cross section is between 0.2 to one and one to one.

Abstract: A backwashable filter includes a generally cylindrical housing, an inlet opening into the housing and an outlet opening from the housing, a cylindrical filter basket within the housing and arranged between the inlet and the outlet openings, and a backwashing arm bearing against the inside of the filter basket and being rotatable around the inside face of the filter basket. The filter basket comprises a perforated core a filter medium wrapped around the perforated core and a perforated flexible outer clamping band wrapped around the outside of the filter medium with tensioning means to apply tension to the clamping band to clamp the filter medium tightly against the perforated core. This clamping band constrains the filter medium and so prevents it flexing with rotation of the backwashing arm and this enhances its life. The performance of the filter is also increased since leakage of the liquid to be filtered around edges of the filter medium is more easily prevented particularly when split clamping rings are also provided.

Abstract: Cholesterol oxidase is activated by adding a surface-active compound with lipophilic and hydrophilic properties. This method is advantageously used for detecting and for determining cholesterol and cholesterol esters in body fluids by oxidising the cholesterol with oxygen in the presence of cholesterol oxidase to cholestenone and hydrogen peroxide and detecting the hydrogen peroxide by peroxidase-catalysed oxidation of an oxidation catalyst, wherein the cholesterol oxidase is activated before it is used by adding a surface-active compound with lipophilic and hydrophilic properties. The diagnostic composition for carrying out this method is distinguished by consisting of an absorbent carrier or a plastic film which is impregnated with cholesterol oxidase, a system for detecting H2O2, buffer and at least one surface-active compound with lipophilic and hydrophilic properties, or contains these embedded in it.

Title: Physical or electrical valve measuring unit - uses optical sensor supplying pulses, suitable for multiplexing, to oscillator circuit resonating according to detected light level
Inventor: NORDENSKJOLD K
IPC: A01J7/00
Filed: 1981-12-02
Abstract: The sensor contains converters (2,3) from optical to electrical energy and vice-versa and also at least one electrical oscillator circuit (4) having a resonant frequency or Q value dependent on the value being measured. Optical energy in the form of pulses is fed to and from the sensor via an optical fibre. The pulse duration is shorter than the periodic time of the resonant oscillation. Alternatively, the optical energy is in the form of a sinusoidal signal. A light pulse impinges on an interceptor (2) of the sensor consisting of one or more photodiodes. The resultant voltage drives a current through the sender component (3), e.g. a l.e.d. The oscillating circuit (4) modulates this current so that the intensity of the emitted light varies according to the fading or resonant frequency of this circuit (4). The measured value can be for position location, power, pressure, liq. level, flow rate, temp., voltage, current, or a magnetic field.
